Quadratic equation:4x^2 = 9 (x - 3)(x + 4) = 0 2x^2 - 5x + 2 = 0 are examples of quadratic equations, for they can all be written in the form ax^2 + bx + c = 0 where a ?? 0. They each have two solutions, which can be found in a variety of ways first dividing by 4 to get x^2 = 9/4. From which x = 3/2 or x = -3/2. In the second example, as the product of the two factors (x - 3) and (x + 4) is zero, then either x - 3 = 0 or x + 4 = 0, from which x = 3 or x = -4 In the third example, 2x^2 - 5x + 2 = 0

Consider, for example, the line of reasoning to find the value of x to satisfy the equation 3(x - 4) = x - 6. Multiplying out the bracket gives 3x - 12 = x - 6 Adding 12 and taking away x gives 3x - x = 12 - 6 Simplifying gives 2x = 6 Dividing by 2 gives x = 3 Then x = 3 is the solution of the equation.
